To all whom it may concern;

Be it known that I, HENRY V. DUNHAM, a citizen of the United States, residing at Mount Vernon, in the county of Westchester and State of New York, have inventedcertai n new and useful Improvements in Processes of Treating Nuts and Product Thereof, of which the following is a specification.

The present invention relates to cooked peanuts. or other nuts, which also may be salted if desired, and has for its object to produce cooked nuts which are much less liable to decomposition or spoiling than those heretofore produced by somewhat analogous procedure, and embraces both the process and the product produced thereby. For the purpose of illustration, peanuts will be hereinafterreferred to, hot it is to be understood that other Varieties of nuts may be treated, as herein described, with the production of useful products.

In the manufacture of salted peanuts it Specification of-Lettersratent I Application filed January 22, 1919. Serial No. 272,547.

r and placed in has heretofore been the customto' first blanch the nuts after which the meatsare placed in a bath of oil, peanut oil or olive oil havand theoilv then heated to a temperature suflicient to operation the 'nuts' are removed from the bath of oil, drained, a'ndthen sprinkled with 1 salt. or rolled in salt, whereby a suilicient amount of salt adheres to the surface of the nuts to give the desired fla'vor,-and the nuts are then usually placed in paraflined bags or envelops and are ready for sale. In some cases the hulls are taken oflthe nuts and the thin skin is left on the \meats.

I have now discovered that a superior article can be produced, if instead offthe pea nut oil or olive oil heretofore generally used,

a heavy mineral oil, highly purified, be substituted. As a preferred oil to employ, parafiinum liquidum may be mentioned, it being understood that a hi hly purified mineral oil, free -or substa'nti5ly-free from unsaturated hydrocarbons, should'be used.

In the preferred form of the rocess the peanuts are first shelled in any suitable manner, and the brown skins preferably removed, after which they are placed in the bath of paraflinum liquidum heated to a tm-( At the end of-the cooking pregnated, especially the surface portions of ac erly cooked, and the become rancid upon standing,

NUTS AND PRODUCT THEREOF.

Patented am it, rare.-

perature of about 280 to 300 F., andthe nuts are then held in this liquid, at the temperature stated, until the peanuts are propdesired color is pro- 58) duced. The peanuts are then removed from the bath of hot Oll, drained and rolled' in salt in the usual manner, whereby a certain amount of salt will. adhere to the nut meats,

which are then ready for packaging and co shipping or selling. i

The nuts treated according to the present invention are much superior tothose pro-' duced by the prior processes above referred to, since the paraflinuni liquidum does not 66 and it will be understood that after the nuts are treated the receptacles, it may be a considerable time before they reach the ultitime peanut 70 oil or olive oil is liable to undergo ranoidification.

The parafiinum liquidum may be used over and over, until it has taken up a substantial amount of peanut oil from the pea- 7E5 nuts under treatment, whereupon it should be purified from ester-oils before further use. a

The nuts treated will be found to beximeach of the nuts, w1th paraflinum liquidum which acts to prevent oxidation and rancldlfication of the vegetable oil in the interior of the nuts. r

WhatI claim is: '85 F 1. A process of treating nut meats which comprises subjecting the same to'the action of heavy purified mineral 011 at a cooking temperature until sufiiciently cooked and I 2. In the manufacture of salted peanuts, the step of subjecting blanched peanuts to a a bath of parafiinum liquidum at a temperature of about 280 F. to 300 F. until cooked. I

3. Cooked nut meatsat least partially impregnated with heavy purified mineral oil. 4. Cooked shelled peanuts, the outer portions of which are impregnated with asealin coat of parafiinum liquidum. v n testimony whereof I aflix'my signature. .100
